Flowserve”s Guardian 3000 electronics cooling pump is designed for use in cooling computer processors and graphics chips in high-end consumer personal computers. Measuring approximately 90 mm (3.54 in) in length and 36 mm (1.42 in) in diameter, the Guardian 3000 is the smallest pump ever developed by Flowserve. An overhung centrifugal, nonmetallic, magnetic-drive, seal-less pump, the Guardian 3000 uses patented motor technology and innovative design to achieve the small form factor necessary to fit microcomputer and other electronic package applications. The pump is powered by an integral brushless 12-volt DC motor, and is designed for a minimum five-year maintenance-free life. Collaboratively designed and manufactured by members of the company”s Memphis, Tenn.; Vernon, Calif.; and Dayton, Ohio facilities, the unit has successfully completed tens of thousands of hours of endurance testing and more than 40,000 cycles of on/off tests.
